I can set my camera to increase saturation, contrast, and sharpness to get the look out of the lens without editing software. I could technically state I had not altered the picture.
Most people do not know enough about cameras to set there color to neutral before taking a picture, I don't know if this is intentionally deceptive, or just ignorance.
My monitor is calibrated, as is my software. When I post things for sale they are the exact color they are in my tank. If your monitor is off, that is on you, I did my best.
As someone who has been in the professional photography world since 96', and who worked at a lab editing photo's, and who studied print making in school, most of the photo's I have seen in this hobby are altered. If you want to make a list, list the ones who don't, it will be much easier.
